Abstract

Upaya pengendalian dan pemberantasan PMK di Indonesia jika dilaksanakan dengan program vaksinasi dengan kecepatan seperti yang berlangsung saat ini maka akan menyebabkan waktu pemberantasan yang lebih lama dan kerugian ekonomi yang besar. Perbaikan program vaksinasi dengan kecepatan yang ideal selain dapat memperpendek waktu pemberantasan juga akan memberikan dampak keuntungan ekonomi yang sangat besar. Berdasarkan hasil studi ini direkomendasikan agar upaya pengendalian dan pemberantasan PMK di Indonesia sebaiknya program yang dilaksanakan mengacu kepada skenario vaksinasi dengan kecepatan yang ideal. Dalam penyusunan dan pelaksaan program pengendalian di Indonesia dapat menggunakan program pengendalian yang dikembangkan di Filipina sebagai bahan pertimbangan karena sudah terbukti secara efektif berhasil memberantas PMK dari negara kepulauan seperti di Indonesia

Abstract

Avian orthoreovirus (ARV) is widespread and found in almost every commercial poultry farm and other poultry species. Virus isolation from local isolates is necessary to obtain vaccine seeds that are homologous to viruses in the field.  The R&D Laboratory of PT Vaksindo Satwa Nusantara successfully isolated ARV from field cases. Inoculation of SPF Embryonated Chicken Eggs (ECE) is the protocol used to evaluate virus titer, especially to calculate the antigen titer of vaccine prototype candidates. The gross pathology of chicken embryos infected with ARV to evaluate virus growth has not been widely reported. This study aims to observe the gross pathology of chicken embryos infected with ARV to measure the virus titer using infectivity test such as the embryo infectious dose 50 (EID50). The virus suspension was diluted from 10-1 to 10-6 then dilutions of 10-4 to 10-6 were inoculated each into five ECE. Incubated ten days and observed for embryonic death. The observations found the embryonic death on day seven. Pathological changes in the embryos are stunted, thin feather, oedema, and less allantois fluid compared to control of uninfected embryo. The results of the embryos necropsy showed cardiac necrosis, greenish liver, and gelatinous exudate in the abdominal cavity.Keywords - Avian Orthoreovirus, Embryonated Chicken Eggs, Embryo Pathology, EID50.

Abstract

This study was conducted to explore the potential of adjuvant for the production of immunoglobulin Y (IgY) as antistreptococcosis in layer chicken with mass production orientation. Enterococcus faecalis which causes streptococcosis in the red tilapia was selected as a candidateantigen. The production of immunoglobulin Y (IgY) was carried out on Isa Brown layer chickens and aged around 20 weeks. Furthermore, thechickens were grouped into four groups (A, B, C, and D groups), each consisting of three chickens based on the type of adjuvant, while twochickens were used as a control group. Each group was treated by giving MONTANIDE ISA 71R VG adjuvant (A), Freund's adjuvant (B), aluminum potassium sulphate adjuvant (KAl(SO4)212H2O) concentration of 50 ppm in pH 7 (C), and only antigens without adjuvant (D). Chickens were kept for 35 days and each week was checked for presence the IgY antigen in the serum and egg yolk. Booster was conducted on 14th and 28th days of maintenance. The results showed that IgY in treatment group A was detected on day 28 in the serum and day 35 in the yolk. Whereas the treatment group B could be detected on day 35 in the serum. However, the IgY was not detected in the serum and yolk in C, D, and control groups until the end of the maintenance. Based on the results, it can be concluded that the appearance of IgY in serum and yolk in a relatively fast time is obtained in the combination of Enterococcus faecalis antigen with the emulsion of water-in-oil adjuvant (SEPPICMONTANIDE ISA 71R VG) compared to the other types of adjuvant that use in this study.

Abstract

Background Specific immunoglobulin Y (IgY) is widely used in immunotherapy, with expanding applications in body care products. Topically applied influenza-specific antibodies may provide an alternative strategy for preventing respiratory infections. Objective This study aimed to evaluate the stability and biological activity of influenza-specific IgY in various body care products. Methods The biological activity of influenza-specific IgY was evaluated in various body care products at different concentrations. Commercial face mists contained 5% and 10% w/v IgY, face mists and nasal sprays contained 0.5% w/v IgY, lip balm, sunscreen, and hand cream contained 0.1% and 0.25% w/v IgY. The products were stored at room temperature for four weeks, and organoleptic changes were monitored weekly. IgY activity was assessed by enzyme-linked-immunosorbent-assay (ELISA). Results In both face mist products, the aroma gradually became fishy, the color remained stable, and turbidity increased. The biological activity of IgY was still detectable by ELISA at concentrations of 0.5%, 5%, and 10%. In nasal spray, no changes in aroma, color, or turbidity were observed, but IgY activity was not detectable. In lip balm, sunscreen, and hand cream, only slight color changes occurred without any change in aroma, and IgY activity was not detected. Conclusion Influenza-specific IgY retained biological activity in face mist formulations at higher concentrations (≥0.5%) despite observable changes in aroma and turbidity. In contrast, IgY activity was not detected in nasal sprays, lip balm, sunscreen, or hand cream, suggesting that the formulation type and IgY concentration significantly influence its stability and detectability in body-care products.

Abstract

Background Avian influenza (AI) and Newcastle disease (ND) are major poultry diseases in Indonesia, where monitoring of vaccination efficacy commonly relies on the hemagglutination inhibition (HI) assay. The HI assay requires viral antigens, which are generally obtained commercially from PUSVETMA. However, independent antigen preparation would be beneficial for private laboratories. Objective This study aimed to prepare and validate in-house AI and ND antigens as HI assay reagents. Methods Viruses were propagated in embryonated chicken eggs (ECE), inactivated using buffered neutral formalin (BNF), precipitated with polyethylene glycol (PEG-6000), and preserved with glycerol. Validation was conducted by parallel HI testing of 24 chicken sera for AI and 22 chicken sera for ND using both in-house and PUSVETMA’s antigens. Antibody titers were analyzed using analysis of variance (ANOVA), with sensitivity (Se), specificity (Sp), and kappa (κ) tests performed for agreement.   Results ANOVA revealed no significant differences in geometric mean titers between in-house and PUSVETMA’s antigens (P<0.05). Both the AI and ND in-house antigens demonstrated Se and Sp values of 100% and κ values of 1, indicating perfect agreement. Conclusion These findings confirm that in-house AI and ND antigens are comparable to their commercial counterparts and can serve as reliable and cost-effective reagents for HI testing in private laboratories.
